2. The "release cycle" problem: Any high quality rules that are incorporated into SpamAssassin are not distributed until the next release. Since rules and code are tied together, the release cycle for rules is too long. Submitted rules are not distributed while they are most effective, and rules lose their effectiveness too quickly.'

3. \[added by LorenWilton\] The instant an actual rule is posted on the user's list, it will lose about 80% of its effectiveness, usually within about 16 hours. Within a week it will be virtually useless. Sometimes the rule will regain some effectiveness a few months later, and in rare cases posting a rule will not affect the hit rate. But in general, public posting in a readable forum of a rule body will negate the usefulness of the rule almost instantly.' |

4. \[added by BobMenschel from others' discussion\] SA rules development handles rules aimed at spam in English best, since most SA rules developers that feed the distribution system speak and correspond in English, and the great majority of the testing corpora are based in English. We're not as good at developing, validating, testing, or scoring rules in other languages. |
